Abstract

fetched live from OpenAlex

To help drivers safely enter the arterial road from the access road, the authors develop a crash warning system for vehicles in right‐turn scenario based on DSRC (dedicated short range communications). Drivers’ right‐turn behaviours from an access road to an arterial highway are considered in the system. Warning algorithms were tested with field data and DSRC on‐board and roadside equipment. Corresponding outliers filter shows a reliable performance. In this system, right‐turn process is divided into three phases: turn‐in, keep‐steady, and turn‐out. Based on the field data, they establish regression models for each phase. Model results show that: (i) the overall duration of the three phases of the right‐turn manoeuvre increases with the amount of cars coming from left on main artery; (ii) the amount of cars that are influenced by the arterial traffic increases the duration of first two phases, but decreases the last phase duration; (iii) the longer the first two phases last, the shorter the last phase would be; and (iv) drivers tend to decelerate before turning right when there are more than two cars coming from left.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
